MUSCLE FATIGUE ANALYSIS IN MINIMALLY INVASIVE SURGERY
… as limited work volume and degree of freedom, minimally invasive surgery (MIS) is ergonomically challenging to surgeons than traditional open surgery. Specifically, MIS can expose performing surgeons to excessive ergonomic risks including muscle fatigue that may lead to critical errors in …

Tissue classification from electric impedance spectroscopy for haptic feedback in minimally invasive surgery
Haptic feedback is missing in teleoperated surgical robots creating a sensory disconnect from the surgeon and their patient. This thesis proposes using the electric impedance of tissues, instead of the traditionally used mechanical impedance, to develop haptic feedback for surgical robots. Electric …

Analysis of Ergonomics and Highly Non-linear Dynamics of Surgical Motions and Muscle Activations in Minimally Invasive Surgery
Minimally invasive surgery (MIS) is becoming increasing popular and widely adopted on account of relative post-operative advantages (shorter hospital stays, less scarification, trauma and post-operative pain) it offers patients when compared to open surgery. Nonetheless, the surge in demand for MIS …

Outcomes of clinical pathway in laparoscopic and open surgical treatments for gastric cancer patients : Patients selection for fast-track program through retrospective analysis
… the complete rate from the clinical pathway in minimally invasive and open surgery for gastric cancer, and to establish a subgroup of patients who can be applied by the early recovery after surgery program through this retrospective analysis. Methods. In this retrospective study, we analyzed 425 …

Microsurgical techniques in regenerative periodontal therapy
Microsurgery and minimally invasive surgery should be considered a true reality in periodontal regenerative surgery. Several clinical trials have shown their efficacy and predictability in the treatment of intrabony defects. In 1992 microsurgery was introduced to the field of periodontics. The main …
